I have following data in a lookup table.

ID	Category	Deleted
1	Electronics	False
2	Personal Care	True
3	Smartphones	False

I have an editable UltraGrid that allows users to select a category for each row, using a column having UltraComboEditor to display categories.

Users can only select categories that are not deleted i.e. Electronics and Smartphones. However, if the row already has a record that references deleted category (Personal care, Id=2), it should be added to the list of items in the UltraComboEditor

For all new rows, it UltraComboEditor should only contain non-deleted categories.

My Category column is similar to EmployeeID column in the following snapshot:

How can I accomplish that?

Thanks

Hello,

In order to make sure that I understand your requirement correctly I have several questions:

For already initialized records in the grid, the UltraComboEditor would have to show all items including the deleted if some of the records contain them, however, the user will not be able to select them?

When a new row is added to the grid at runtime the UltraComboEditor would have to display only values that have Deleted property equal to false?

Answering these questions is going to be highly appreciated.

Thank you for your cooperation.

Looking forward to hearing from you.

Sincerely,

I would like users to be able to keep/select deleted categories for existing rows, but once they have modified the existing record and selected a non-deleted category, they should not be able to go back to select the deleted category. For all new rows, user should not be able to selected a deleted category.
